The York County coroner ruled on March 23 that Flanscha's cause of death was blunt-force trauma to the torso, with the manner accidental.

Anthony's autopsy was conducted the day after his death, but the cause of death wasn't released until Monday because the coroner's office was awaiting results from additional testing, Coroner Pam Gay said.

Flanscha had been with the department since 1999, and Anthony had been there since 2010. They were among a group of four firefighters in the building dealing with hot spots from a fire the day before. The two other firefighters suffered injuries that were not life-threatening.
